Now that the device has been out for a while, many users are complaining of the same thing. Samsung must be listening, because it is now pushing out a patch to the Samsung Galaxy S10 and S10 Plus that allegedly will make the sensor faster and better than ever (via SamMobile).
The biometrics software update which includes the new patch is distributed via the Galaxy Store. Since that’s the case, there’s no way to manually trigger the update; you have to wait around until it makes its way to your device.
Does the patch actually make the fingerprint sensor better? That’s tough to say: many users on Reddit who have received the patch seem to think it does, but there’s always the concern of “the placebo effect” with these kinds of things. We’ve seen other users online with the patch who say they notice no difference, for example.
Regardless of whether the patch really does wonders or not, at least Samsung isn’t ignoring the problem and is instead trying to figure out ways to make the user experience better.
